use:
(1) Modified thermosetting acrylic coatings are used in resins and alkyd resins to improve weather resistance and film formation;
(2) Improve the weather resistance of PVC-based coatings;
(3) Improve the adhesion, water resistance and solvent resistance of the non-woven fabric coating of the adhesive;
(4) Improve the water resistance of vinyl acetate-based latex and the adhesion of acrylic latex;
(5) Plastic, fiber modification, etc.
In terms of synthesis, it is mainly used as a comonomer for reactive thermoplastic elastomers and thermosetting acrylic coating resins;
In terms of modification, it is mainly used as a modifier for various coatings, adhesives, and plastic alloys, such as modified thermosetting acrylic coatings, polyvinyl chloride coatings, alkyd resins, etc. These coatings have better water resistance and film formation Sex. The modified adhesive and non-woven coatings have better adhesion, water resistance and solvent resistance. In the field of coatings, glycidyl methacrylate is a more oily functional monomer, which can be well with other acrylics. Ester monomer copolymerization, the content and distribution of such monomers in the polymer are easy to control, and can be made into various acrylic powder coatings.
In the field of medicine, it can be used as separation medium or adhesive. For example: a continuous bed chromatography column of cross-linked polyglycidyl methacrylate synthesized by precipitation polymerization "in-situ" polymerization, after chemically modifying it, the spacer arms containing 11 carbon atoms were obtained respectively And high-efficiency affinity column without spacer arm-bound protein A: N-methylglycine and glycidyl methacrylate adduct (NTG-GMA) or N-phenylglycine and glycidyl methacrylate Ester adduct (MPG-GMA), used as an adhesive for teeth.
Glycidyl methacrylate (GMA) is widely used in many fields such as acrylic powder coatings, latex coatings, textile and leather finishing agents, rubber vulcanization, adhesives, photosensitive materials, organic synthesis, polymer synthesis, medicine and so on.
In addition, it can also be used to modify a variety of materials. The product has excellent comprehensive performance, non-toxic, and the quality reaches the level of similar products of Osaka Organic Chemical Company in Japan. It has passed the technical appraisal of the former Ministry of Chemical Industry and has been industrialized for the first time in China. Mainly used for powder coatings, but also for thermosetting coatings; fiber treatment agents; adhesives; antistatic agents; vinyl chloride stabilizers; rubber and resin modifiers; adhesives for ion exchange resins and printing inks.
Glycidyl methacrylate is irritating to the skin and mucous membranes and is almost non-toxic. Because it contains both carbon-carbon double bonds and epoxy groups in its molecule, it can undergo free radical reaction and ionic reaction.Therefore, it has high reactivity and can carry out different reactions separately. It is widely used in many fields such as medicine, light-sensitive materials, organic synthesis and polymer modification. The resulting product has excellent anti-ultraviolet, water and heat resistance characteristics, and is an important fine chemical raw material.

3. Hazard information
Hazard introduction: colorless transparent liquid. Flammable! Steam is toxic, monomer can irritate eyes, skin, and respiratory system
1): This product will seriously irritate the eyes and cause corneal damage
2): This product will irritate or burn the skin
3): The gas inhaled by this product will irritate the upper respiratory tract. At high temperatures, high concentrations of steam cause harm or even death
4): If swallowed this substance will cause throat burn, gastrointestinal irritation and ulcer
Chronic hazard warning: Studies on live animals have shown that GMA affects sperm morphology and quantity, although this is not caused by occupational exposure. Occupational exposure limit is 1ppm
Effects of overexposure: oral LD50 is 700mg/Kg, which is lower than the middle level; skin absorption (rabbit) LD50 is 480mg/Kg, direct contact with this substance will cause severe skin burns, and harmful doses of long-term exposure and absorption can be fatal. Overexposure to high-temperature steam can cause death.
4. Treatment method
Eyes: Keep the eyelids open and rinse immediately with water for at least 15 minutes. Medical treatment
Skin: Immediately flush skin with plenty of water and remove contaminated clothing and shoes, and send to medical treatment. Do not use contaminated clothing before washing, and destroy contaminated shoes.
Inhalation: If inhaled, remove victim to fresh air.
If swallowed: Do not induce vomiting, as the surging gastric juices may be sucked into the lungs. Drink plenty of water or cattle and seek medical attention immediately. It is strictly forbidden to feed food to unconscious persons.
5. Fire prevention measures
Flash point (closed cup): 85℃
Combustion range (mol%, 100℃): 1.1 lower limit
Auto-ignition temperature: no relevant data
Decomposition temperature: no relevant temperature
Hazard of combustion: Due to the low volatility, the fire hazard of GMA is not great; but the monomer is unstable at high temperature, and the storage container should have vent holes of suitable size to reduce this hidden danger. Its steam is toxic
Extinguishing media: Extinguish with carbon dioxide, dry powder, water spray, alcohol-resistant foam
Fire extinguishing equipment and recommendations: Firefighters should wear full protective clothing and wear positive pressure self-priming respirators
Other information: Remove the packaging container near the fire or spray with water to cool it
6. Accidental leakage treatment
Emergency treatment: immediately isolate the leaking or dumping area. Keep unrelated people away. Personnel are upwind, ventilating the isolated area before entering. Eliminate all sources of combustion (no smoking, ignition, sparks, flames, non-explosion-proof electronic equipment). Do not touch or pass through the spilled material. If it can be done, the dumping should be stopped immediately. Wear appropriate personal protective equipment when cleaning up. Small area leakage: Cover with dry sand or polypropylene matrix absorbent and put in a container for later disposal. Large leaks: dike before leaking liquid for later disposal. Prevent entry into drains, sewers, and basements. Plan to properly treat wastewater before flushing with water; do not use large amounts of water for flushing when there is no biodegradable and approved industrial equipment. It is best to use a vacuum tank truck.
7. Handling and storage
Handling process: Avoid contact with skin and eyes. Wash thoroughly after changing clothes. After the handover, you should take a shower and wash the clothes of the handover. Personal clothes and work items should be stored separately. Where the product is stored and used, food, beverages, and cigarettes are not allowed to be carried, stored, and used; wash your face and hands before using food, beverages, and cigarettes.
Storage process: Keep this substance in a cool, ventilated place. Should be stored at 15 ℃ to avoid solidification and lead to the separation of the polymerization inhibitor, do not come into contact with pig iron, mild steel, copper and brass that cause harmful polymerization and monomer discoloration.
